Our son asked “Hey, is that one of the Doctors?” and the world smiled, or at least we did. Good to see him recognizing a favorite. Tom Baker starts a recurring role in this episode. He plays Wyvern, a “spirit guide” in Limbo who helps Marty get accustomed to the afterlife and learn his trade.
Baker’s part of a powerhouse cast this week. Hugh Laurie plays the villain, and in smaller parts, there’s Martin Clunes, Richard Todd, and Wanda Ventham. I should probably know these three from other roles than in eighties Who, but I’m like that. Another Who connection: it’s one of two episodes from this series to be directed by Rachel Talalay, who would later direct seven episodes in the Peter Capaldi years. Earlier, she’d directed the Tank Girl movie and she’s more recently been calling the shots on several of the CW’s superhero series.
“Mental Apparition Disorder” is a loose rewrite of a celebrated episode from the original run, “A Disturbing Case,” and that episode’s co-writers, Mike Pratt and Ian Wilson, get a credit at the end. They don’t spend nearly as much screen time on Marty impersonating the criminal hypnotist-psychiatrist in this version as in the original, and it isn’t as funny, but it involves a lot more hypnotized patients, so it has its own charm. Our son made the very disturbing observation that he even liked it better than the original, but in fairness, this one does include a lot more shouting. That said, an earlier scene where Marty tries to get the hypnotized Jeff’s attention by bellowing in his ear really is funny.
